Description
API: PyObject* PyBytes_Join(PyObject *sep, PyObject *iterable)
Similar to sep.join(iterable) in Python.
sep must be Python bytes object.
iterable must be an iterable object yielding objects that implement the buffer protocol.
On success, return a new bytes object. On error, set an exception and return NULL.

UPDATE: Don't accept sep=NULL.
It's different than PyUnicode_Join(NULL, iterable) which treats NULL separator as a whitespace (' '). This PyUnicode_Join() behavior is not documented. The PyUnicode_Join() documentation only says:
Join a sequence of strings using the given separator and return the resulting Unicode string.
